Pre-requisite: Google Cloud Security
Google Cloud Security Scanner is a security scanning tool offered by Google Cloud Platform that checks for common vulnerabilities in web applications hosted on GCP. It scans for a wide range of security issues such as cross-site scripting (XSS), missing security headers, out-of-date software, and other common vulnerabilities. It works by simulating an attack on the web application and analyzing the responses to identify vulnerabilities.
It can be integrated with Google App Engine, Compute Engine, and Kubernetes Engine. After the scan is complete, it generates a report highlighting all vulnerabilities found and providing recommendations on how to fix them, in this way it allows for improving the security of the web application. It’s a useful tool for security professionals and developers to identify and remediate potential vulnerabilities in their web applications running on GCP infrastructure.
Here are some key terminologies used in Google Cloud Security Scanner:
- Vulnerability: A weakness or flaw in a web application that can be exploited by an attacker to gain unauthorized access or perform unauthorized actions.
- Cross-Site Scripting (XSS): A type of vulnerability that allows an attacker to inject malicious code into a web page viewed by other users.
- Flash Injection: A vulnerability that allows an attacker to inject a malicious flash object into a web page.
- Mixed Content: A vulnerability that occurs when a web page is loaded with both secure (HTTPS) and insecure (HTTP) content, potentially exposing sensitive data to eavesdropping.
- Security Headers: HTTP headers that can be used to enhance the security of a web application. Examples include the “X-XSS-Protection” header, which can help prevent XSS attacks, and the “Content-Security-Policy” header, which can help prevent cross-site scripting and other types of code injection attacks.
- Out-of-Date Software: This refers to software that is not updated to its latest version and can contain known vulnerabilities that could be exploited by attackers.
- Scan Report: This is the report generated by the scanner after the security scan, which contains the vulnerabilities found and its recommendations to remediate them.
Benefits of Google Cloud Security Scanner
Google Cloud Security Scanner provides several benefits, including:
- Automated Vulnerability Scanning: It automatically scans web applications for common vulnerabilities such as cross-site scripting and SQL injection, reducing the effort and time required for manual testing.
- Improved Security: It identifies potential security issues and provides recommendations for remediation, helping to improve the security of web applications.
- Compliance: It helps organizations meet compliance requirements by identifying security vulnerabilities that could impact sensitive data.
- Integration with Google Cloud Platform: The security scanner integrates with Google Cloud Platform, making it easy to use and manage within the Google Cloud ecosystem.
- Cost-Effective: Google Cloud Security Scanner is a cost-effective solution for organizations looking to improve the security of their web applications.

The tool also provides reporting and management capabilities, as well as a large library of plugins to extend its functionality. OWASP ZAP is widely used as part of a comprehensive security program to reduce the risk of web application security incidents and meet regulatory compliance requirements.
Limitations of Google Cloud Security Scanner
Google Cloud Security Scanner is a powerful tool for identifying vulnerabilities in web applications running on the Google Cloud Platform, but it has some limitations:
- Limited Scan Coverage: Google Cloud Security Scanner is only able to scan the parts of the application that are publicly accessible. It cannot scan internal network components or back-end systems.
- False Positives: Google Cloud Security Scanner may sometimes report false positives, which are vulnerabilities that don’t actually exist. This can happen if the scanner is unable to accurately interpret the behavior of the application.
- Complex Configurations: Google Cloud Security Scanner may have difficulty scanning applications with complex configurations, such as multi-tier architectures or the use of custom technologies.
- Scan Speed: Large applications can take a long time to scan, which may impact performance and limit the frequency with which scans can be run.
- Reliance on Google Cloud Platform: Google Cloud Security Scanner is only able to scan applications running on the Google Cloud Platform. It is not a general-purpose security scanner that can be used to scan applications running on other platforms.
These limitations should be taken into consideration when using Google Cloud Security Scanner and a comprehensive security program that includes multiple security tools and techniques is recommended to reduce the risk of web application security incidents.
